Abstract
A series of acetyl pyrenes and pyrenyl ynones with and without tert-butyl groups showed distinct mechanofluorochromism (MFC). Four pairs of polymorphic solids were found out of six compounds and interestingly, each of them showed hypsochromic, bathochromic or off-to-on MFC. The MFC properties were rationalized by categorizing the packing schemes into herringbone, sandwich, beta and gamma motifs depending on the relative contributions of C⋅⋅⋅C (or π-π) against C⋅⋅⋅H contacts. The bulky tert-butyl and trimethylsilyl groups served not only to reduce the number of aggregation patterns but also to prohibit the complete back reactions in solid state. Our results suggest that the simple pyrene derivatives may be promising candidates for a novel group of mechanically-sensitive materials.

Abstract
Ruthenium-catalyzed butadiene-mediated benzannulation enabled the first synthesis of 3,10-(di-tert-butyl)rubicene and its N-doped derivatives as well as preliminary studies on their photophysical properties. Unlike the parent rubicene and 3,10-(di-tert-butyl)rubicene, which adopt classical herringbone-type packing motifs in the solid state, the N-doped congener 7 b displayed columnar packing with an alternating co-facial arrangement of aromatic and heteroaromatic substructures.

Abstract
Sterically hindered N,2,7-tri- tert-butylpyrene-1-carboxamide treated with n-BuLi, i-BuLi, s-BuLi, and n-HexLi in THF in the presence of TMEDA and air afforded trans- N,2,7-tri- tert-butylpyrene-10-alkyl-9-hydroxy-9,10-dihydropyrene-1-carboxamides in 63-74% yield. Trifluoroacetic acid promoted dehydration of these compounds gave 10-alkyl derivatives of the starting amide in 79-89% yield. The minor products of this reaction were deamidated compounds, 4-alkyl-2,7-di- tert-butylpyrenes.
